the displayed backtrace is perl's call stack, it might give some information as to where perl is dying.

You might also have success by trying to find the minimum amount of code needed to cause the segfault. Try commenting out about 1/2 of the module loads (you can use =pod and =cut to comment out a block of code) and do a binary search. Even with a thousand modules, that would only take approx 10 steps.
